Does Calithe Jewelry Turn Your Skin Green? 316L Steel & PVD Gold Test

The science behind 316L surgical stainless steel vs cheap copper/brass jewelry, and why Calithe chains, rings, and bracelets never tarnish or stain skin.

Why Cheap Jewelry Turns Skin Green (And Why 316L Steel Never Does)

Green skin staining is caused by copper oxidation reacting with sweat and skin acidity in cheap brass or copper-core jewelry. Calithe constructs its chains, bracelets, and rings from 316L surgical-grade stainless steel—which contains zero reactive copper—making it 100% hypoallergenic and physically incapable of turning your neck, wrist, or finger green.

What Is 18K PVD Vacuum Gold Plating?

Instead of traditional wet dip-plating that wears off in a few showers, Physical Vapor Deposition (PVD) bonds real 18K gold titanium nitride molecules into the microscopic pores of the 316L steel inside a high-temperature vacuum chamber. The result is a finish up to 10x thicker and more corrosion-resistant than standard gold plating.

Shower, Gym & Ocean Pool Care Tips

You can wear Calithe 316L chains, bracelets, and rings in the shower, at the gym, and in swimming pools without fading. After saltwater or heavy chlorine exposure, simply rinse with fresh water and pat dry with a microfiber cloth to keep the mirror polish gleaming.
